Spinach Parmesan Squares
Spinach Parmesan Squares are the perfect combination of spinach, savory parmesan, garlic, breadcrumbs, and butter that even the most vegetable-averse kids can’t resist. The dinner table struggle is real. If you have a picky eater at home, you know how challenging it can be to get them to even look at a vegetable. This savory, cheesy, and absolutely delicious recipe is one side dish that my kids not only eat but actually ask for.
These little bites of goodness are the perfect solution for busy families and they are incredibly easy to make. I always make a big batch because they are perfect for quick snacks, easy side dishes, or even packing in a lunchbox. Plus, they freeze beautifully! It’s a family favorite at our house, and I hope it will be at yours too.
Spinach Parmesan Squares Key Ingredients
Let’s take a closer look at the ingredients that make up this dish.
Spinach
I always use frozen spinach (usually 12 oz bags) that I then thaw and strain. The microwavable bags are quick and easy to thaw. I pop them in the microwave for 50-75% of the recommended time and then strain with a colander. You will want to get most of the water strained but not completely dry. It’s important to note that I add quite a bit of spinach to this recipe because I wanted it to be on the “healthier” side but you can reduce the amount, if desired. (If you do cut back on the spinach, you do not have to alter the remaining ingredients; however, the cooking time should be reduced. Check with a thermometer to make sure it is around 165 degrees F.)
Parmesan Cheese
I typically use grated parmesan cheese for this dish.
Eggs
Eggs act as a binder for this recipe. I like to have them room temperature so they blend well with the other ingredients.
Seasoned Dry Bread Crumbs
Seasoned dry bread crumbs add substance, texture, and seasoning to the spinach squares.
Melted Butter
Melted butter gives the dish a rich savory flavor.
Spices
We use salt, pepper, garlic powder, and onion flakes to add flavor to the dish.
How Should I Store Spinach Parmesan Squares?
This is one of my favorite recipes to make ahead and have ready to go in the freezer.
- To Store: Let the spinach squares cool slightly in the pan. Once they are no longer steaming, cover the dish and store it in the refrigerator for up to 4 days.
-
To Freeze: For best results, allow the squares to cool completely in the fridge for a few hours first. Then, you can either keep them in an airtight, freezer-safe container or wrap the pan tightly in aluminum foil or Press’n Seal. Don’t forget to label it with the date! They will keep for 2-3 months.
-
To Reheat: Thaw frozen squares in the refrigerator overnight. To warm, place them in a 350°F oven (covered with foil to prevent drying out) until heated through. You can also warm them straight from the freezer, but you’ll need to add extra baking time. Be sure to remove any cling wrap or Press’n Seal first!
Tips
- Spinach – You will want to get most of the water strained but not completely dry (see video). It’s important to note that I add quite a bit of spinach to this recipe because I wanted it to be on the “healthier” side but you can reduce the amount, if desired.
- Eggs – The eggs will incorporate into the mixture more evenly at room temperature.
- Storage – Store spinach squares in an airtight container in the refrigerator for up to 4 days.
